We began working out of our cars! Not many start-ups can say that. Beginning in September 2003, two people came together to start a business that would be built on common sense, fairness and fun.

Design Mechanical opened for business on September 1, 2003. Many thought it wouldn’t last in such a poor economy. However, in our first full year of business, our revenue was over $9 million! Five years later, the revenues grew to over $20 million. It certainly didn’t grow that quickly on good looks alone;. It was the career-long relationships of both Bill Iler and Mike Chieppo, along with a great office staff and highly experienced field crew that helped this company survive the start-up, and grow to what it is today.
